Terminal distance (branched structure analysis)

Purpose

Reports the distance between the starting point of a given branch order (centripetal order) and a termination (end), as well as the termination type and coordinates.

Analysis results

Tree: Each tree selected for the analysis is assigned a unique number starting at 1.

Termination: Identifies the ending type assigned to the termination. If ending types were not assigned while tracing in Neurolucida or Neurolucida 360, quantities will not be shown.

 

Normal Ending (N) Default
High Ending (H)

Ending located at the top of the current section. Depending on the orientation of the sections, the process may continue into another section.

  • Use the Z Meter to determine the Z value of the ending.
Low Ending (L) Ending located at the bottom of the current section.
Incomplete (I) Use to label arbitrary endings, endings that disappear for unknown reasons, endings that should be audited later.
Origin Ending (O)

Indicates the directionality of the tree.

  • Use this setting if you have been tracing towards the cell body and find that your "ending" is actually the beginning of the process.

Neurolucida Explorer keeps track of directionality to apply branch orders.

Midpoint (M) Ending of a long branch that is indeterminate at the time it is placed.
Generated (G) When Neurolucida or Neurolucida 360 is unable to determine an ending type, it assigns a "Generated" ending. This can happen during editing when the ending type originally assigned is no longer valid, or a new ending is created. Examples include editing to relocate the origin ending, which leaves the original origin unassigned, or splitting a branch, which creates new endings. You may need to evaluate the generated endings and assign the appropriate ending type.
Branch (B) Describes a terminal segment point that is a node (bifurcating or trifurcating). The Branch ending type will only be seen in segment analyses.

Distance: Distance between the origin of a given branch and a termination point (end) using the centripetal order.

Termination coordinate: Coordinate (X,Y,Z) of the ending.
